Abstract
The utility model relates to transfusion equipment, in particular to an extension tube for transfusion. The extension tube for transfusion comprises a transfusion tube body, and is characterized in that an adapter which is directly connected with a nipple of an injection syringe is arranged at the upper end of the transfusion tube body, and a Murphy's dropper is arranged below the adapter. A filtering device is arranged below the Murphy's dropper and is internally provided with a filter with a filter membrane. The extension tube for transfusion has the beneficial effects that the adapter at the upper end of the transfusion tube body is directly connected with a nipple of the injection syringe, thereby avoiding pollution, being safe and sanitary; and the Murphy's dropper arranged below the adapter can buffer less air in the injection syringe, and prevent small bubbles from entering a human body, and does not need to exhaust gas in the injection syringe for a long time, thereby being simple to operate and saving time.
